Thank you! You are absolutely correct about the limitations, although it was made in TIC-80 which have a similar set of restrictions to Pico-8. The game was limited to 16 colors total and a resolution of 240 by 136 px, which probably only helped keep the scope managable for the Jam. Sometimes restrictions are great :)
I'm glad you liked it and relieved someone else understood it and found the main mechanic fun!
